About shared text and libraries:  On the Amiga, the shared libraries are in
the ROM -- they are the equivalent of system calls on UNIX.  Stdio and other
"libc" routines are still linked in with the executable and therefore exist
multiple times, so AmigaDOS and UNIX are very similar in terms of memory
usage.  It is possible to write your own shared library, but it requires
special programming techniques.  On UNIX System V release 3, this has been
done, and there is a shared version of libc available; the supplied UNIX
utilities have been compiled with it.  It is not the default because it is
not possible to use most debugges on a program using a shared library.
